No foreground object this time, just a sense of flow and movement. I used a very long exposure (90 seconds) to capture the flow of the water back to the ocean. This was made possible with a 10 stop ND filter and a 3 stop ND grad filter for the sky. Also added a warming filter to the sky to enhance the color contrast between the top and bottom..Camera and lens: Pentax K10d + Sigma 10-20mmISO: 100Aperture: f9.5Exposure: 90 secondsManfrotto tripod and remote shutter release10 stop ND filter, 3 stop ND grad filter, warming filter
